The best we can reasonably do at present is to rotate the file on login, so that the information from the previous session is available for debugging, but the file won't grow out of control.
Users who log out rarely should still be OK; a reboot from time to time is still necessary in order to apply updates, and this file should not grow very quickly. If a program outputs too much data to this file, that's a bug which should be fixed. -- .xsession_errors file grows out of control & saturates disk space https://launchpad.net/bugs/60448 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
